Abstract: A theoretical study of the vehicle design parameters affecting the vehicle stability was investigated. The vehicle speed and the rate of change of the steering angle are the most significant parameters that affect the vehicle stability. An experimental test rig simulating the mechanical steering system was designed and constructed, and a control algorithm was developed. At a threshold value, a control signal was activated automatically to control the vehicle speed and lock the steering wheel in the critical direction. Accordingly, controlling the lateral acceleration may prevent the vehicle rollover at critical speeds and thus it may improve the vehicle stability.
